A framework to create Scriptable Objects that are a tree of many sub-nodes.

Setup

This repo is dependant on L3-typeTree, and must be added as packages together to function.

Add both packages to the package manager in Unity:

https://github.com/Less3Design/L3-typeTree.git
https://github.com/Less3Design/L3-hierarchy.git

Usage

A hierarchy is made up of at least 2 object types, a L3Hierarchy and L3HierarchyNodes.

Heirarchy

The L3Hierarchy object is what holds all of our nodes. It does not maintain any hierarchy structure itself.

using Less3.Hierarchy;

[CreateAssetMenu(menuName = "Less3/Examples/Hierarchy", fileName = "NewExampleHierarchy")]
public class ExampleHierarchy : L3Hierarchy
{
    // settings that affect the entire heirarchy can go here
}

Nodes

L3HierarchyNodes make up the content of your tree. They function similair to Unity's Transform component, where they maintain a parent and list of children.

The [TypeTreeMenu] attribute is used to place this node into the "add new node" menu. The type parameter should match the heirarchy type you plan to use this node inside.

using Less3.Hierarchy;
using Less3.TypeTree;

[TypeTreeMenu(typeof(ExampleHierarchy), "Nodes/MyExample")]
public class ExampleNode : L3HierarchyNode, IHierarchyNodeTitle
{
    public string customTitle;
    public string NodeTitle => string.IsNullOrEmpty(customTitle) ? name : customTitle;
}

Tips

• Different node types can parent to each other.
• Nodes can be styled using interfaces found in L3HierarchyNodeStyleInterfaces.cs
• A node type can be used in multiple hierarchy types. You just need to define mutiple [TypeTreeMenu] attributes on the node.
